Tens of thousands of exhibitionists stripped down to their underwear to ride the world’s subways in an annual event designed to make people laugh.
The No Pants Subway Rides took place today in dozens of cities, organized by pranksters Improv Everywhere.
It might have been light relief for passengers in Brisbane with temperatures topping 31 degrees Celsius (89F), but not so much for the residents of Calgary where the mercury is set to plunge to -20 degrees Celsius next week.
These practical jokers in Prague, London, Berlin and Munich appeared to raise plenty of eyebrows among their fellow passengers, but did not seem to produce too many laughs.

Today’s event was the 17th time commuters bared all in the name of comedy.
People took off their trousers, shorts and skirts to take tubes and subways in their pants in 60 cities covering 25 countries.
The idea started in New York in 2002 and has grown into a global gathering ever since.

In January 2016, the event took off for the first time in Moscow, Russia.
It was not without controversy when police tried to book participants with instigating mass public disorder.
But the incidents amounted to nothing when it as argued the organisers’ goal had been to make people laugh.
